Alameda Sheriff’s Deputy Allegedly Kills Couple In Dublin, California

Kelly said Williams grew up in an affluent home, graduated from college “with honors,” and was “really a remarkable young person.” He previously was an officer with the Stockton Police Department, which ultimately let him go after he failed to pass his probationary period due to what Kelly described as issues with “his ability and his skill set” rather than his conduct.

A spokesperson for Stockton police told BuzzFeed News they couldn’t discuss Williams’s separation with the department because it was a “personnel matter” but confirmed that he was employed there from January 2020 to January 2021.

When he was hired by the Alameda sheriff’s office, the department conducted “a complete and thorough” background check, as well as a psychological exam, and didn’t see anything that concerned them.

“His background was immaculate,” Kelly said.

But sometime in the last several months, “significant events” must have happened in his life that his supervisors were unaware of, Kelly said. He noted that Williams was clearly “disturbed” and in crisis when he called officials to surrender.

While at the Alameda County sheriff’s, Williams was assigned to a courthouse in Oakland and occasionally picked up shifts at the Santa Rita Jail in Dublin, Kelly said. On Tuesday, he worked his normal shift at the courthouse and then reported to the jail where he worked overtime until 11 p.m.

Kelly told BuzzFeed News investigators are trying to determine what happened in the hour and 45 minutes between him leaving the jail and showing up at the house, which is just a few minutes away by car. Officials believe the victims were asleep when Williams showed up at the house. A child and two other family members were inside the residence at the time.

Kelly said they’re looking into “all angles” to determine whether there was a romantic relationship, a business relationship, or some other kind of connection to the couple. He confirmed that Williams, who is Black, is not a relative of the victims, who are both Asian.

“There was some relationship that was formed rather recently within the past year and we’re looking into what that is,” Kelly said. “What was it, I don’t know and I think we will get an answer to that.”
